I am an assistant professor at UNC Chapel Hill as of August 2013. Previously I was an assistant professor at Stony Brook University. I completed a Ph.D. at U.C. Berkeley with Jitendra Malik, and have had the chance to work with many wonderful people.

I am interested in all aspects of computer vision and related problems in other fields. My thesis was on shape and object recognition in images using a new take on deformable templates. I also work on large scale machine learning algorithms for object recognition and detection, image retrieval, recognizing and synthesizing human action in video, recovering human body poses from photographs, detecting and identifying human faces in images, detecting vehicles in images, and more...


Note for potential graduate students.

  • Note for potential graduate students: You do not need to contact me. UNC admissions are done centrally. See this link. Unfortunately I can not respond to very many e-mails about applying. That said I am always interested in very well qualified large-scale machine learning and computer vision students.
